IMPROVEMENT IN MACHINE S FOR MAKING WOODEN GUTTERS.

Specification forming part of LettersPatent No. 157,703, dated December15, 1874; application filed October 5, 1874.

To all whom it may concern:

Be it known that I, HENRY A. STONE, of Worcester, in the county ofWorcester and State of Massachusetts, have invented certain new anduseful Improvements in Machines for Making Wooden Gutters; and I dohereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art towhich it pertains to make and use the same, reference being had to theaccompanying drawings, and the letters of reference marked thereon,which form a part of this specification.

Figure 1 of the drawing represents an end view of myinvention Fig. 2, aside elevation of the same; Fig. 3, a side view of the hollowcylindrical saw detached from the machine; Fig. 4, an end view of thesame, showing the cutter-bar attached.

Similar letters of reference indicate corresponding parts.

My invention relates to improvements in that class of machines employedin making wooden gutters, in which a cylindrical saw is used to out outthe required cavity; and my invention consists in the arrangement andcombination of parts, as will be hereinafter more fully described.

A in the drawing represents a table or platform, made of metal or othersuitable material, and supported on standards a. The saw B, which ismade inthe form of a hollow cylinder, is attached by bolts or rivets toa cutterbar, b, said bar being connected to a station ary shaft, 0, uponwhich shaft the bar is free to work. Projecting from one side of the barb, and at right angles thereto, is a small arm, 0, to which is swiveledone end of the shaft D, the other end being connected eccentrically tothe wheel E. This wheel E is connected to the driving-shaft d and pulleye, the shaft and pulley working in bearings formed in the project ingarms ff. Secured upon either side of the table A are slotted standardsG, in which the ends of the bar F work and are guided, said bar beingprovided with a pressure-plate, H. This bar F and pressure-plate H arecapable of being adjusted to the thickness of the gutter by theregulating-screws g 9. Upon one side of the table A is an adjustablegage, I, and upon the other side, opposite said gage, a spring oryielding bar, J. This spring or yielding bar J presses against the sideof the gutter, which, in connection with the gage I, prevents thepossibility of any side or lateral motion of the gutter as it passesover the table, and the pressure-plate H, keeping the gutter down uponthe table or bed, holds it in proper position in relation to the saw,while a semirotary motion is imparted thereto.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In combination with the hollow cylindrical semi-rotary saw B, thepressure-plate H, working in slotted standards G G, adjustable gage I,and spring or yielding bar J, substantially as and for the purpose setforth.
